Description

Technical Field

[0001] The utility model belongs to the technical field of building exterior wall insulation boards, and in particular relates to a building exterior wall insulation board connection structure. Background Art

[0002] The building exterior wall insulation board is a building material installed on the facade of the building, which is used to integrate multiple functions such as energy saving, heat preservation, fire prevention, sound insulation, and decoration. When in use, the insulation board needs to be installed on the facade of the building through a connecting structure. The existing building exterior wall insulation board has three installation methods: press-on installation, hanging installation, and buried installation. Among them, the press-on installation is to directly stick the insulation board on the exterior wall of the building, and fix it with special adhesive glue or fixings; the hanging installation is to fix the insulation board on the frame of the building's exterior wall with a metal hanging piece; the buried installation is to install the insulation board in the concrete structure, and finally spray the waterproof layer and the finishing layer. However, there are several problems with the existing installation method. First, in order to avoid the extrusion and fall off between the insulation boards caused by thermal expansion and contraction, an expansion gap needs to be reserved during installation. In winter, the expansion gap is large, which is easy to affect the insulation effect; second, the adjacent insulation boards are independent of each other and cannot provide support for the adjacent insulation boards. Especially for the hanging-type installed insulation boards, the insulation boards are prone to fall off. Therefore, it is necessary to optimize and upgrade the connection structure of the insulation board. Utility Model Content

[0008] In a preferred embodiment, a splicing hole is formed on the splicing avoidance portion to cooperate with a splicing pin to connect two adjacent splicing avoidance portions.

[0009] In a preferred embodiment, the center of the second insulation board has a bolt connection groove to cooperate with the connection bolts on the outer wall of the building to fix the second insulation board to the outer wall of the building.

[0010] In a preferred embodiment, the first insulation board and the second insulation board have a plurality of crisscross buffer grooves on one side facing the building exterior wall.

[0011] In a preferred embodiment, the longitudinal section of the buffer groove is arc-shaped.

[0012] In a preferred embodiment, the first insulation board and the second insulation board have a rough surface facing away from the building exterior wall.

[0013] In a preferred embodiment, the contact surfaces of the extension portion and the matching portion have anti-slip patterns.

[0014] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0015] 1. When the insulation board in the utility model is in use, the first insulation board and the second insulation board are matched in such a way that the first insulation board and the second insulation board are adjacently connected, so that during installation, the matching portion can cover the extension portion, so that only the second insulation board needs to be fixed, and the first insulation board does not need to be fixed with a workpiece under the restriction of the matching portions of multiple second insulation boards, thereby reducing the complexity of the insulation board installation and facilitating the installation of the insulation board on the exterior wall of the building by the staff.

[0016] 2. As a preferred embodiment of the utility model, through the cooperation of the extension part and the matching part, multiple second insulation boards can be used around the first insulation board, and only the second insulation board needs to be fixed. At the same time, during the installation process, considering the deformation of the insulation board caused by thermal expansion and contraction, while reserving the expansion gap, through the cooperation of the extension part and the matching part, the entire insulation layer can have no gap perpendicular to the exterior wall of the building, thereby improving the insulation performance of the insulation board.

[0017] 3. As a preferred embodiment of the present invention, the buffer groove can further enhance the ability of the insulation board to cope with the problem of thermal expansion and contraction. When the insulation board expands and deforms due to heat in a hot environment, the buffer groove can absorb the extrusion pressure caused by the deformation, thereby preventing the insulation board from breaking due to the expansion of the insulation board.

[0038] According to one embodiment of the utility model, Figure 1 , Figure 2 , Figure 3, Figure 4 , Figure 5 , Figure 6 As shown, a connection structure of an insulation board for an exterior wall of a building comprises a first insulation board 1 and a second insulation board 2. The edge of the first insulation board 1 has an extension portion 11, and the edge of the second insulation board 2 has a matching portion 21 that matches the shape of the extension portion 11. The extension portion 11 and the matching portion 21 cooperate to form a transition board with the same thickness as the insulation board. The extension portion 11 forms a splicing avoidance portion 12 at the four top corners of the first insulation board 1. When the insulation board in the utility model is in use, the first insulation board 1 and the second insulation board 2 cooperate in a manner that the first insulation board 1 and the second insulation board 2 are adjacently connected, so that during installation, the matching portion 21 can cover the extension portion 11, so that only the second insulation board 2 needs to be fixed, and the first insulation board 1 is restricted by the matching portions 21 of multiple second insulation boards 2, and does not need to be fixed with a workpiece, thereby reducing the complexity of the insulation board installation and facilitating the installation of the building exterior wall insulation board by the staff.

[0039] Alternatively, if Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown in FIG. , the longitudinal sections of the extension portion 11 and the matching portion 21 are triangular.

[0040] Alternatively, if Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown, the longitudinal sections of the extension portion 11 and the matching portion 21 are stepped.

[0041] In addition, the longitudinal sections of the extension part 11 and the matching part 21 may also be other shapes. Through the cooperation of the extension part 11 and the matching part 21, multiple second insulation boards 2 can be used around the first insulation board 1, and only the second insulation boards 2 need to be fixed. At the same time, during the installation process, considering the deformation of the insulation board caused by thermal expansion and contraction, while reserving the expansion gap, through the cooperation of the extension part 11 and the matching part 21, the entire insulation layer has no gap perpendicular to the outer wall of the building, thereby improving the insulation performance of the insulation board.

[0042] Furthermore, the extension portion 11 and the matching portion 21 are provided with corresponding connection pin holes 22, so as to cooperate with the connection pin shaft to connect the first insulation board 1 and the second insulation board 2. The connection pin hole 22 can connect the first insulation board 1 and the second insulation board 2 as a whole through the connection pin shaft, thereby improving the integrity of the insulation board, further improving the energy, heat preservation, fire prevention, sound insulation and other properties of the insulation board, and at the same time, reducing the shedding of the insulation board, thereby improving the safety and reliability of the installation of the insulation board.

[0043] Furthermore, a splicing hole 23 is formed on the splicing avoidance portion 12 to cooperate with a splicing pin to connect two adjacent splicing avoidance portions 12, thereby further enhancing the connection tightness and integrity between adjacent insulation boards.

[0044] In a preferred embodiment, the center of the second insulation board 2 has a bolt connection groove 24 to cooperate with the connection bolts on the building outer wall to fix the second insulation board 2 on the building outer wall. This facilitates the connection between the second insulation board 2 and the building outer wall, so that when in use, the second insulation board 2 can be fixedly connected by connecting rivets on the building outer wall, thereby improving the convenience of connecting the second insulation board 2.

[0045] A preferred embodiment, as Fig.11 As shown, the first insulation board 1 and the second insulation board 2 have a plurality of crisscross buffer grooves 25 on the side facing the building exterior wall. Furthermore, the longitudinal section of the buffer groove 25 is arc-shaped. The buffer groove 25 can further increase the insulation board's ability to cope with thermal expansion and contraction. When the insulation board is deformed by thermal expansion in a hot environment, the buffer groove 25 can absorb the extrusion force generated by the deformation, thereby preventing the insulation board from breaking due to the expansion of the insulation board.

[0046] Furthermore, the first insulation board 1 and the second insulation board 2 have a rough surface facing away from the building exterior wall, thereby improving the wall-hanging ability of the insulation board and the bonding effect with the building exterior wall.

[0047] In a preferred embodiment, the contact surfaces of the extension portion 11 and the matching portion 21 have anti-slip patterns, which can improve the pressing ability of the matching portion 21 to the extension portion 11 and prevent the first insulation board 1 from escaping from the encirclement of the second insulation board 2.
